The atomic number of an element is the number of protons in the nucleus of an atom of that element.

Atoms with the same number of protons, but a different number of neutrons are called isotopes.

Answer:

In physics and chemistry, the atomic number of a chemical element is the total number of protons that each atom of that element has. It is usually represented with the letter Z.

The atoms of different elements have different numbers of electrons and protons. An atom in its natural state is neutral and has an equal number of electrons and protons. A sodium atom (Na) has an atomic number of 11; It has 11 electrons and 11 protons. A magnesium atom (Mg), has an atomic number of 12, has 12 electrons, 12 protons and a uranium atom (U), which has an atomic number of 92, has 92 electrons and 92 protons.

DerKrebs [107]

Answer:

a network of proteins that holds homologues together.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

The synaptonemal complex is a network of proteins that holds homologues (homologous chromosomes) together.

Generally, a synaptonemal complex (protein lattice) is formed between homologous chromosomes during mitosis and meiosis. Also, synaptonemal complex is important for the formation of the four sister chromatids referred to as tetrads.

Furthermore, the synaptonemal complex (protein lattice) has a tripartite structure which comprises of the following components;

I. SC protein-1 (SYCP1).

II. SC protein-2 (SYCP2).

III. SC protein-3 (SYCP3).

In conclusion, the synaptonemal complex plays a significant role in synapsis, recombination and chromosome pairing.

What causes a sea and land breeze?
viktelen [127]

☁️ Answers ☁️

☁️ During the day, the sun heats up both the ocean surface and the land. The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse. ☁️

❤️

☁️ Land: The land breeze is a coastal breeze at night blowing from the land to the ocean. It is caused by the difference in the rates of cooling of the land and of the ocean. Once again, the bigger the difference in temperature between the two, the stronger the wind ☁️

☁️ Sea: A sea breeze is created when a low pressure forms over the coast. The sea has a greater heat capacity than land, meaning it requires more heat to change its temperature. Therefore, during the day, as the sun’s warm rays shine down on the earth, because of the difference in heat capacity, the land heats up faster than the sea. ☁️

Hope it helps.

Have a nice day noona!~  ̄▽ ̄❤️
